IMPROVEMENT IN STAlR-CARPET FASTENERS.

. face view of the same.

Similar letters of reference indicate corresponding parts in both figures.

This invention relates to a new and very simple means for securing stair carpets and cloths in position.

It consists of a concavo-convex short plate, having nail-holes at its upper and lower ends, so that it can be placed against step and riser of the'stairs, and fastened thereto by nails or pins that pass through said nail-holes. The plate is provided with a raised portion or boss for holding the nail-heads at a distance therefrom, so that the nails may be readily Withdrawn, if desired.

In the accompanying drawing, the letter A represents my improved carpet-fastener. It is a plate made of sheet or cast metal or of other suitable material, concavo-convex in vertical cross-section, and of about two inches in length. It has nail-holes a and b at its upper and lower ends respectively, as shown. A boss or raised ring or portion, 0, surrounds each nail-hole a b, so that the nail-heads cannot come in direct contact with the face of the plate.

The carpetis placed over the stairs in usual manner. The plate A is then placed against the carpetinto the angle formed by the step and riser of the stairs, so that the convex side of the plate bears against the carpet, as clearly indicated in Fig. 1. Nails or pins d d are then driven through the holes a b and through the carpet into tLe riser and step of the stairs, until the nail-heads reach the bosses or projections c. The carpet is thus securely held without requirin g expensive stair-rods. Itcan be readily removed by introducing the claws of a nailextractor of suitable kind between the nailheads and the plate A, to facilitate which the boss 0 is left on the plate, as already stated.

The plate being convex holds the carpet at the junction of riser and step duly rounded, as shown in Fig. 1, and does not crowd it into the vertex of the angle between said riser and step. Carpets are injured if folded into sharp angles. By having the nail-holes at the top and bottom of the plate, the latter is fastenedto the carpet and to the stairs at points where.

the carpet lies flat against the wood-work.

I claim as my invention- 1. As a new article of manufacture, the concavo-convex plate A, having nail-holes a and b at the upper and lower ends respectively, and adapted to secure a stair-carpet and to hold the same rounded at the angles, substantially as specified.

2. In a stair-carpet fastener having nailholes a b, the boss 0 formed around each nailhole, substantially as and for the purpose specified.
